Answer 2

1. $\star \: \rm \: 1000 \: litres...option \: d$
2. $\star \: \rm2 \pi \: rh...option \: c$
3. $\star \: 2 \rm(lb + bh + lh)....option \: b$
4. $\mapsto \rm \: \frac{ \pi {r}^{2} h}{2 \pi \: r h} \\ \bf \: canceling \: some \: terms \\ \star \: \frac{ \pi}{2} (c)$
5. $\star \: \frak{volume}... \tt \: option \: d$
